Updated catalog of the Chilean wedge-shaped beetles (Coleoptera: Ripiphoridae) with the first records of Macrosiagon flavipennis (LeConte) in Chile

The biology and ecology of wedge-shaped beetles (Coleoptera: Ripiphoridae) are scarcely known in the Neotropical realm. Chilean species of this beetle family are currently represented by two genera: Macrosiagon Hentz, 1830 and Ripiphorus Bosc, 1791, and three species, only known from their type localities. Here, we present an updated catalog of Chilean Ripiphoridae, along with the new distributional and biology records. Also, Macrosiagon flavipennis LeConte, 1866 (Ripiphorinae: Macrosiagonini) has been reported for the first time in Chile. We discuss the reasons for the presence of M. flavipennis in urban areas, the state of knowledge of the endemic species presents in Chile in relation to their distribution and the opportunity to use opportunistic records to better understand their natural history

Nuevos registros y distribución actualizada de Myopa metallica Camras 1992 (Diptera: Conopidae: Myopinae) en Chile usando métodos de colecta integrativa

Myopa metallica Camras1992 is a parasitic fl y, endemic to Chile, whose distribution was unknown. In this study, four new localities are reported between the Atacama and Metropolitan regions using citizen science. Our work breaks down the methodological barriers, providing a distribution for a rare and conspicuous thick-headed fly.Myopa metallica Camras, 1992 es una mosca parásita, endémica de Chile, cuya distribución era desconocida. En este estudio se reportan cuatro nuevas localidades entre la región de Atacama y Metropolitana usando ciencia ciudadana. Nuestro trabajo rompe las barreras metodológicas, proporcionando una distriución para una especie de mosca conspicua y rara

Primeros registros de Meromacrus cactorum (Diptera: Syrphidae) de Chile, con nuevos datos biológicos

The syrphid genus Meromacrus is widespread in the Neotropics, but its presence in Chile has been confirmed just recently. Adults pollinate, and larvae are saprophagous of vegetal materials. In this note, we report Meromacrus cactorum Ricarte et al. for the first time from Chile. New data on adult habitats and flower visitation are also provided for this Meromacrus. Adults were observed on flowers of the cacti Opuntia ficusindica, Cumulopuntia sphaerica, and the vulnerable Browningia candelaris. Species distribution and pollinator potential are discussed for M. cactorum.El género Meromacrus (Diptera: Syrphidae) está ampliamente distribuido en la región Neotropical, pero su presencia en Chile ha sido confirmada recientemente. Los adultos polinizan, mientras que las larvas descomponen materia orgánica asociada a plantas. En esta nota reportamos por primera vez en Chile a Meromacrus cactorum Ricarte et al. Se proporcionan nuevos datos sobre el hábitat y las flores visitadas por los adultos de M. cactorum. Los adultos fueron observados sobre flores de los cactus Opuntia ficus-indica, Cumulopuntia sphaerica, y la especie vulnerable Browningia candelaris. Se discute la distribución de M. cactorum, así como su potencial polinizador.RBS thanks Agencia Nacional de Investigación y Desarrollo (ANID) for his PhD doctoral scholarship (CONICYT 21160404) and postdoctoral grant ANID-FONDECYT 3200817, as well as Instituto de Ecología y Biodiversidad de Chile (IEB), for the grant FB170008.
